Abstract
A motion sensor incorporates an internal light source, typically a super bright LED and an optical projection system visible to an observer standing in the motion sensor coverage zone(s) to simplify orientation of the sensor on installation. A multi-lens system or an arrangement of small windows in front of the LED projects a visible light pattern that mimics the detection pattern of the motion sensor to an observer standing in the detection zone and looking at the sensor.
Claims8
A sensor system comprising:
- an enclosure;
- a sensing element installed in the enclosure having a detection zone exterior to the enclosure;
- an alignment light within the enclosure;
- optical projection elements installed on or within the enclosure and relative to the alignment light to project light emitted from the alignment light in a pattern which is visible to an observer when the observer in positioned in the detection zone.
